- A body of mass m is attracted toward a 11.1 kg mass, 31.5 cm away, with a force of magnitude 6.60 10-8 N. Find m. can you also add the units!Imagine that Chris, whose mass is 45 kg, has fallen into a crevasse in a glacier. Chris's partner Pat, whose mass is 65 kg, has thrown a rope to Chris and intends to lift Chris out by holding on to the other end of the rope while sliding down the glacier’s icy slope which is tilted at an angle of 35o with respect to the horizontal. Assume that Pass has used some camping equipment to cobble together a pretty good pulley to change the rope’s direction at the lip of the crevasse. Also assume that Chris hangs freely when suspended below the lip of the crevasse. Is it possible for Pat to pull Chris out, considering the likely coefficients of friction involved? Pat has a 30-kg backpack. Could this help?A tutor told me that the answer to 1b was 10N but I don't understand why it would be 10N for the tension. If that is correct could someone break it down for me?
- Crates A and B have equal mass. Crate A is at rest on an incline that makes and angle of theta = 22.22 degrees horizontal, while crate B is at rest on a horizontal surface. Write an expression for the ratio fo the normal forces, A to B in terms of theta?Hello, could you please help me with this question. I need second (In what direction must the force (tension) act on the yo-yo?), and third ( What exerts the force?)(a) Forces represented completely by 2AB, 3BČ, 4AČ act along the sides of triangle ABC. Find their resultant and the point where its line of action cuts AB and BC. (b) Show that the resultant of forces AB, CB, 2CD and 2AD acting along the corresponding sides of quadrilateral ABCD, is represented completely by 6QP where P divides BD in the ratio 1: 2 and Q bisects AC.
